Multi factor authentication rule-based intelligent bank cards

ABSTRACT

System, method, and computer program product to implement four factor authentication rule-based intelligent bank cards, by receiving valid authentication information for a card associated with an account, verifying that a captured image of a person presenting the card matches an image of an authorized user of the account, analyzing the captured image to detect an emotion of the person, and performing a predefined operation to control access to the account upon determining that the detected emotion satisfies an emotion rule associated with the account.

BACKGROUND

The present disclosure relates to banking, and more specifically, to four factor authentication rule-based intelligent bank cards.

Fraud has historically plagued the financial industry. Debit cards currently use two-factor authentication, namely the card itself and a pin number associated with the card/account. However, if the card is stolen and the PIN becomes known, an unauthorized user may withdraw funds from a victim's account at an ATM machine. Therefore, there exists a need for enhanced security measures for debit cards.

SUMMARY

Embodiments disclosed herein provide a system, method, and computer program product to implement four factor authentication rule-based intelligent bank cards, by receiving valid authentication information for a card associated with an account, verifying that a captured image of a person presenting the card matches an image of an authorized user of the account, analyzing the image to detect an emotion of the person, and performing a predefined operation to control access to the account upon determining that the detected emotion satisfies an emotion rule associated with the account.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

FIG. 1 illustrates a system for four factor authentication rule-based intelligent bank cards, according to one embodiment.

FIG. 2 illustrates a method for four factor authentication rule-based intelligent bank cards, according to one embodiment.

FIG. 3 illustrates a data structure to store predefined rules and actions based on detected emotions, according to one embodiment.

DETAILED DESCRIPTION

Embodiments disclosed herein provide enhanced security and additional functionality for debit cards by applying actions based on emotion detection. Embodiments disclosed herein leverage existing cameras in ATM machines to perform a third and fourth authentication factor, namely analyzing an image of a person presenting a card to the ATM machine to verify that the person is an authorized user on the account associated with the card, and analyzing the person's expressed emotions to detect suspicious behavior. For example, if the person is scared, nervous, or agitated, predefined rules associated with the account may control, limit, or restrict account access by performing any number of predefined actions. The predefined actions include, but are not limited to, completely restricting access to the account, imposing a maximum withdrawal, alerting an account holder of record, prompting the account holder to enter a security code sent to the account holder via SMS or email, and the like.

Stated differently, the third and fourth factors are what you are and how you act. Embodiments disclosed herein apply facial recognition as the third factor to ensure that the person presenting the debit card is an authorized user under the account by comparing a captured image of the person at the ATM machine to stored images of authorized users. The images may be stored on a remote server, on the card itself, or any other feasible location. Once the facial recognition process is successfully completed, embodiments disclosed herein implement facial expression algorithms as the fourth authentication factor. If the facial recognition algorithms determine that the card holder is worried, scared, or any other emotion based on the algorithm, a predefined action may be performed. Virtually any action that can be configured an automated is completed as a predefined action responsive to the detected emotions.

Additionally, embodiments disclosed herein allow for the application of custom rules to each user's account, or to shared accounts held groups such as family members or businesses. For example, person A may be able to withdraw $500, while person B may have no limit, but an SMS alert is sent whenever a withdrawal occurs. Therefore, embodiments disclosed herein expand the usage of ATM cards, debit cards, or any type of instrument used to access accounts, from the current “one card one user” paradigm to a “one card to many users with controls in place” paradigm. Advantageously, embodiments disclosed herein may enhance security without weakening existing security measures, such as the PIN number scheme. The rules may be defined by the user, the financial institution, or both.

FIG. 1 illustrates a system 100 for four factor authentication rule-based intelligent bank cards, according to one embodiment. The networked system 100 includes a computer 102. The computer 102 may also be connected to other computers via a network 130. In general, the network 130 may be a telecommunications network and/or a wide area network (WAN). In a particular embodiment, the network 130 is the Internet.

The computer 102 generally includes a processor 104 connected via a bus 120 to a memory 106, a network interface device 118, a storage 108, an input device 122, and an output device 124. The computer 102 is generally under the control of an operating system (not shown). Examples of operating systems include the UNIX operating system, versions of the Microsoft Windows operating system, and distributions of the Linux operating system. (UNIX is a registered trademark of The Open Group in the United States and other countries. Microsoft and Windows are trademarks of Microsoft Corporation in the United States, other countries, or both. Linux is a registered trademark of Linus Torvalds in the United States, other countries, or both.) More generally, any operating system supporting the functions disclosed herein may be used. The processor 104 is included to be representative of a single CPU, multiple CPUs, a single CPU having multiple processing cores, and the like. The network interface device 118 may be any type of network communications device allowing the computer 102 to communicate with other computers via the network 130. The computer 102 also includes a camera 125 capable of capturing still images and video and a card reader 126. The card reader may be any type of card reader, including, but not limited to, a magnetic strip reader, near field communications (NFC) reader, smart card reader, and the like.

The storage 108 may be a persistent storage device. Although the storage 108 is shown as a single unit, the storage 108 may be a combination of fixed and/or removable storage devices, such as fixed disc drives, solid state drives, SAN storage, NAS storage, removable memory cards or optical storage. The memory 106 and the storage 108 may be part of one virtual address space spanning multiple primary and secondary storage devices.

The input device 122 may be any device for providing input to the computer 102. For example, a keyboard and/or a mouse may be used. The output device 124 may be any device for providing output to a user of the computer 102. For example, the output device 124 may be any conventional display screen or set of speakers. Although shown separately from the input device 122, the output device 124 and input device 122 may be combined. For example, a display screen with an integrated touch-screen may be used.

As shown, the memory 106 contains the authenticator application 112, which is an application generally configured to apply four factor authentication in fulfilling financial transactions. For example, when a user wishes to withdraw funds from an ATM, the authenticator application 112 may require a card, a PIN number, perform facial recognition of the person attempting to withdraw funds, and perform emotion analysis of the person attempting to withdraw funds. The authenticator application 112 may reference the configuration data 115 during multiple steps of a transaction in order to implement different predefined actions responsive to predefined conditions being satisfied. The authenticator application 112 may also include one or more facial recognition and emotion detection algorithms. For example, if the facial recognition analysis fails, the authenticator application 112 may control, limit, or restrict account access according to one or more predefined rules. Generally, any type of financial transaction may be managed by the authenticator application 112, such as wiring funds, issuing checks or other instruments, or making purchases.

As shown, storage 108 contains the configuration data 115, which stores user account information and associated rules for each account. The user account information, in addition to standard data, may include images of authorized users that may be used by the authenticator application 112 as part of the facial recognition analysis. The rules may be rules defined by the financial institution or by account holders. For any given account, multiple people may be authorized to access the account, and different rules may be applied to each person. The rules specified in the configuration data 115 may cause the authenticator application 112 to perform one or more predefined actions upon detecting one or more predefined events. For example, a user may specify that if the facial recognition algorithms fail to match a user to the images stored in the configuration data 115, an SMS containing a code may be sent to a phone number on file with an authentication code that the user can enter to access the account. Additionally, if the authenticator application 112 detects an emotion as part of its emotion analysis, it may reference the configuration data 115 to determine whether one or more rules specify to perform a predefined action. For example, if the emotion analysis indicates that the user is expressing fear, a predefined rule may immediately end the attempted transaction and lock the account pending further authentication.

FIG. 2 illustrates a method 200 for four factor authentication rule-based intelligent bank cards, according to one embodiment. In one embodiment, the authenticator application 112 performs the steps of the method 200. Generally, the method 200 extends authentication techniques to include facial recognition and emotion analysis as additional authentication factors. Users can define any type of rule related to their account. The authenticator application 112 will in turn enforce the rules and corresponding predefined actions, such as limiting an amount of funds that can be withdrawn under specific circumstances.

At step 210, a user presents a card attempting to perform a financial transaction. At step 215, the authenticator application 112 attempts to read data stored in the card to determine whether the card is valid. If the card is not valid, the method 200 ends. If the card is valid, the method proceeds to step 220, where the authenticator application 112 requests that the user enter the correct PIN number to access the account. Generally, at step 220, the authenticator application 112 may request that the user enter any form or type of authentication code. At step 225, the authenticator application 112 determines whether the PIN number received from the user is valid. In one embodiment, the authenticator application 112 may reference the configuration data 115 to determine whether the PIN is correct. The authenticator application 112 may provide the user any number of attempts to correctly enter the PIN number. If the PIN is not valid, the authenticator application 112 may terminate the method 200 after the user has incorrectly entered it a threshold number of times. The financial institution or the user may set limits on the number of attempts that the authenticator application 112 may provide to the user. In other embodiments, authentication information other than PIN numbers may be implemented, such as any type of biometric security information, including but not limited to retina scanning, DNA identification, palm print reading, iris recognition, hand geometry recognition, and fingerprint reading. If the PIN is valid, the authenticator application 112 may capture an image of the user at step 230. At step 235, the authenticator application 112 determines whether the image capture is successful by applying an algorithm to the captured image to verify that the image can be used for facial recognition. If the image capture was not successful, the user may be notified at step 240. At step 240, the user may be asked to look into the camera for another image capture. After a predefined number of unsuccessful attempts, the card may be ejected (or retained by the machine), and the method 200 may end.

If the image capture was successful, the authenticator application 112 may process the image at step 245. In one embodiment, the authenticator application 112 may pull facial recognition data points from the captured image at step 245, for use by facial recognition algorithms. At step 250, the authenticator application 112 determines whether the captured image matches an image stored in the configuration data 115 for authorized users of the card. Generally, the authenticator application 112 may apply facial recognition algorithms to the captured image and the stored images. If the captured image does not match any image stored for the card, the authenticator application 112 may terminate the attempted transaction, and the method 200 may end.

At step 255, the authenticator application 112 may retrieve rules from the configuration data 115 related to the current account. The rules may be stored on the card or in a remote location. The rules may be associated with the PIN and the image of the user, as one card may have multiple user accounts, each account based on the person and their image, PIN, or image and PIN. In addition, different rules may be applied at this step. For example, one user may only have access to draw a specified amount of funds per day, week, year, etc, while another user may only be able to withdraw funds in specified geographic locations. At step 260, the authenticator application 112 determines whether emotion rules exist for the account. If no emotion rules exist, the method 200 may terminate. If the account holder has not specified any emotion rules, they may have decided to allow withdrawals or other transactions to occur without having the authenticator application 112 perform the emotion analysis.

If the account holder has specified emotion rules that should be applied to the transaction through emotion detection, the authenticator application 112, at step 265, processes the image (or video feed) to parse emotions from the image/video data. For example, the authenticator application 112 may determine that the user is nervous, angry, scared, or is exhibiting fear. At step 270, the authenticator application 112 determines whether a rule is associated with an emotion detected at step 265. The user (or financial institution) may implement any number of rules associated with different emotions. Additionally, a catchall emotion may be provided that specifies rules for the authenticator application 112 to apply when the detected emotion does not match an emotion for which a rule has been specified. At step 275, the authenticator application 112 processes the predefined action specified in the rules associated with the detected emotions. Some examples of predefined actions may include, but are not limited to, limiting withdrawal amounts if fear is detected, sending an SMS with an access code to a phone number associated with the account if nervousness is detected, or a catchall emotion may restrict the display of account information on the screen. The authenticator application 112 may continuously monitor the images/video feed to detect emotion and apply rules until the user logs out of the account.

FIG. 3 illustrates a data structure 300 storing predefined rules and actions based on detected emotions, according to one embodiment. As shown, the data structure 300 includes an account number 301, a person 302 corresponding to an authorized user of the account, an account user ID 303, an emotion ID 304, an emotion 305 corresponding to a predefined emotion (or a catchall), and an action 306 corresponding to an action implemented responsive to detecting the corresponding emotion 305. The data structure 300 may also include other data that is not shown, such as images of the users. The rules and actions defined in the data structure 300 may be user defined, or defined by the financial institution. As shown, for example, an emotion rule ID 001 has been defined for user Pete associated with account number 12345. The emotion rule ID 001 specifies that if the person attempting to access the account is scared, the maximum that can be withdrawn from the account is $20. In addition, the balance displayed to Pete may be masked or otherwise limited. For example, a $20 balance may be displayed to Pete, as that is the maximum amount he can withdraw, even though the balance in the account may be greater, such as $10,000. Jonas, another authorized user of account 12345, cannot withdraw any funds if the detected emotion is scared, as $0 is the maximum withdrawal allowed in emotion rule ID 004.

As shown, for account 23456, a catchall emotion rule ID 007 has been defined for user Jason. The catchall serves to cover detected emotions other than a predefined emotion, such as the fear emotion associated with emotion rule ID 008. So while emotion rule 008 specifies that Jason (or someone acting as Jason) can only withdraw $50 if fear is detected, emotion rule 007 specifies that more money can be withdrawn for unspecified emotions. Additionally, emotion rule ID 007 places geographic restrictions on how much money can be withdrawn, namely a $200 maximum withdrawal if the ATM is more than 50 miles from Jason's home address, while a $400 maximum withdrawal may be made if the ATM is less than 50 miles from his home.

Advantageously, embodiments disclosed herein provide enhanced security when authenticating a user attempting to perform a financial transaction by implementing facial recognition and emotion detection algorithms to thwart fraudulent activity. Embodiments disclosed herein ensure that the person attempting to withdraw funds matches an image of an authorized user, and detect emotions of the person to ensure that they are not being coerced into withdrawing funds. Even if an unauthorized user gets past the facial recognition analysis, emotions associated with criminal behavior will trigger the predefined actions to limit the amount of loss, if any, caused.

Aspects of the present disclosure are described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the disclosure. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

Embodiments of the disclosure may be provided to end users through a cloud computing infrastructure. Cloud computing generally refers to the provision of scalable computing resources as a service over a network. More formally, cloud computing may be defined as a computing capability that provides an abstraction between the computing resource and its underlying technical architecture (e.g., servers, storage, networks), enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Thus, cloud computing allows a user to access virtual computing resources (e.g., storage, data, applications, and even complete virtualized computing systems) in “the cloud,” without regard for the underlying physical systems (or locations of those systems) used to provide the computing resources.

Typically, cloud computing resources are provided to a user on a pay-per-use basis, where users are charged only for the computing resources actually used (e.g. an amount of storage space consumed by a user or a number of virtualized systems instantiated by the user). A user can access any of the resources that reside in the cloud at any time, and from anywhere across the Internet. In context of the present disclosure, a user may access applications, such as the authenticator application or related data available in the cloud. For example, the authenticator application could execute on a computing system in the cloud and perform four factor account authentication. In such a case, the authenticator application could perform four factor authentication and store predefined actions related to detected emotions at a storage location in the cloud. Doing so allows a user to access this information from any computing system attached to a network connected to the cloud (e.g., the Internet).

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
